The records of 473 patients with intraoral squamous cell carcinoma, who had managed in Gospel Hospital from Jan. 1979 to Dec. 1985, were reviewed in order to know incidenece, topographic distribution, mode of treatment, and survival rate.
The results of the study are as follows.
1. The age distribution was variable, which was from 7 years old to 88 years old, and the mean age was 54 years, and 80.3 % was occured in men and 19.7 or, was occured in women, especially at tonsil, the ratio of men to women was 10 to 1.
2. Pharynx (21.4 %)1. and tongue (19.7 %) was the most common site of the primary carcinoma in the mouth, and the buccal mucosa (0.8 %), gingiva (3 %), faucial arch (0.6 %), and the lip (4.9 %) showed relatively lower incidence rate.
2. The mean duration, which was defined as the period from symptom onset to first hospital visit, was 10.3 month, especially 26.4 month in lip, below 5 month in gingiva.
3. The size of the carcinoma which was measured on the first visit was from 1 cm to 8 cm, the mean size was 4.4 cm , and in palate, the size (5.1 cm) was usually large and that in the lip was small (3.5 cm).
4. In N-stage, 61.3 % was beyond N-1 at tongue, and high value was shown in pharynx and hypopharynx also. The most common regional metastatic lymphnode was upper posterior cervical lymphnode (42.9 %).
5. In type of treatment, only radiotherapy was 29.4 %, and combined treatment with chemical, surgical, and radiotherapy was 51.0
6. The 2 years survival rate was 39 % in overall. At tongue the 2 years survival rate was 58 % compared with other site. On T-stage, that was 67 %, 43 %, 27 %, 25 % in T1, T2, T3, T4.
7.The 2 years survival rate was 54 % on tha cases without regional lymphonde metastasis, 26 % with metastasis. On N-stage, that was 43 %, 25 %, 13 % in N1, N2, N3.
